Garbage collection in Java is the processes of freeing the dynamic memory used by objects that are no longer being used by an application. In languages such as or C or C++, the developer is often responsible for managing dynamic memory (using malloc and free or new and delete). However, in Java, this task is left …

Solr is the popular, blazing fast open source enterprise search

Hello Lucene users,
On behalf of the Lucene development community I would like to announce the
release of Lucene Java versions 3.0.2 and 2.9.3:
Both releases fix bugs in the previous versions:
- 2.9.3 is a bugfix release for the Lucene Java 2.x series, based on Java
1.4.
- 3.0.2 has the same bug fix level but is for the Lucene Java 3.x series,
based on Java 5.
New users of Lucene are advised to …
The Lucene community has recently decided to merge the development of two of its sub-projects – Lucene->Java and Lucene->Solr. Both code bases now sit under the same trunk in svn and Solr actually runs straight off the latest Lucene code at all times. This is just a merge of development though. Release artifacts will remain separate: Lucene will remain a core search engine Java library and Solr will remain a search server built on top …
The vote is on for what I think is a Lucene first – two simultaneous bug fix releases. Because the Lucene 2 series is the last to support Java 1.4, we are doing a bug fix release for for 2.9 as well as the recently released Java 1.5 required 3.0 release.
A little preview from the proposed release announce:
Important improvements in these releases are a increased maximum number of unique terms in each index

I have some Highlighter work that I keep meaning to finish up (basic support for highlighting ConstantScoreQuerys), and so I have the Highlighter on my mind……
When working with a large scale Lucene/Solr installation, users sometimes run into memory issues or garbage collection performance problems. Its not a frequent occurrence in my experience, but just like life, it happens. Whenever I run into this sort of thing, I’ve come to rely on a variety of free tools to investigate the problem. There are many other free tools I have tried, but over time, I have found the following most useful:
